Elevation and apparent conductivity ranges measured for coastal environmental units mapped along the Port Aransas transect. Elevations were measured using an airborne lidar instrument. Apparent conductivities were measured using a ground-based Geonics EM38 instrument in the vertical (vd) and horizontal (hd) dipole orientations. VBF = vegetated barrier flat, MFH = high fresh marsh, MFL = low fresh marsh, MSH = high salt marsh, MSL = low salt marsh, WTFH = high wind-tidal flat, WTFL = low wind tidal flat. |
